An Energy Performance Certificate is required for a every non-domestic or commercial building when constructed, sold or let. An EPC informs potential occupiers, tenants or buyers about the energy performance of a building. The EPC enables them to consider energy efficiency as part of their investment or business decision.
An EPC must be accompanied by a recommendation report which provides a list of measures on how the energy efficiency of the building can be improved. The recommendation report also shows an indication of the payback period for each of the measures.
An EPC is valid for up to 10 years and is registered and stored on a national EPC database, enabling all potential lessees or purchasers to review the rating.
